Which agricultural emission reduction practice involves applying nitrification inhibitors to reduce N2O emissions from fertilized soils?
Answer: Controlled-release fertilizer with nitrification inhibitors
Nitrification inhibitors slow the bacterial conversion of ammonium to nitrate, reducing the substrate available for denitrification that produces N2O.
In the context of carbon markets, what is 'additionality' for an emission reduction project?
Answer: The emission reduction would not have occurred without the carbon finance incentive
Additionality requires that the emission reductions are beyond what would have happened under a business-as-usual scenario without carbon market revenue.
A utility company installs grid-scale battery storage to increase renewable energy utilization and reduce curtailment. What is the primary emissions benefit?
Answer: Enables dispatch of stored renewable energy during peak demand, displacing fossil fuel peaker plants
Battery storage allows excess renewable generation to be stored and dispatched during high-demand periods, replacing high-emission natural gas peaker plant output.
What distinguishes a 'market-based' Scope 2 accounting method from a 'location-based' method?
Answer: Location-based uses the national average grid emission factor; market-based uses contractual instruments like RECs
The location-based method applies average grid emission factors, while the market-based method reflects contractual claims from instruments like renewable energy certificates (RECs) or power purchase agreements (PPAs).
Which industrial decarbonization technology captures CO2 directly from point sources such as power plant flue gas before it is released to the atmosphere?
Answer: Carbon capture and storage (CCS) at point source
Point-source CCS captures CO2 from concentrated industrial or power generation flue gas streams and transports it for geological storage, preventing atmospheric release.
A transportation company switches from diesel trucks to battery-electric trucks powered by grid electricity. Under what scenario would this switch NOT reduce total lifecycle GHG emissions?
Answer: The regional grid is powered predominantly by coal, producing a high emission factor per kWh
If the electricity grid is coal-dominated with a very high emission factor, the upstream Scope 2 emissions from charging electric trucks may exceed the Scope 1 diesel emissions they replace.
Which type of carbon offset project reduces emissions by capturing and destroying methane from decomposing organic waste at landfills?
Answer: Landfill gas (LFG) capture and destruction projects
Landfill gas projects collect methane generated by anaerobic decomposition of waste and either flare it (converting high-GWP CH4 to lower-GWP CO2) or use it for energy generation.
